Trigger Finger: Causes, Treatments & When to See a Hand Surgeon in Raleigh

Have you noticed your finger catching, locking, or clicking when you bend it? You may be dealing with a condition called trigger finger — one of the most common hand problems we treat at our Raleigh hand surgery practice. The good news is that trigger finger is highly treatable, and most patients find lasting relief with the right care.

What Is Trigger Finger?

Trigger finger, known medically as stenosing tenosynovitis, occurs when inflammation narrows the sheath surrounding the tendon in the affected finger. The tendon — which normally glides smoothly through this sheath — becomes restricted, causing the finger to catch or lock as you try to bend or straighten it.

In more advanced cases, the finger may become stuck in a bent position and require gentle manipulation to straighten — or it may lock in a straightened position entirely.

Any finger can be affected, but trigger finger most commonly involves the ring finger or thumb. When the thumb is affected, the condition is sometimes called trigger thumb.

What Causes Trigger Finger?

Trigger finger develops when there is repeated irritation or inflammation of the tendon sheath. Common contributing factors include:

• Repetitive gripping or grasping motions — common in certain occupations and hobbies
• Diabetes — people with diabetes are at significantly higher risk
• Rheumatoid arthritis — inflammation from arthritis can affect tendon sheaths
• Hypothyroidism — an underactive thyroid is associated with trigger finger
• Gout — uric acid deposits can contribute to tendon inflammation
• Female sex — women are more commonly affected than men

In some cases, no clear cause is identified. Trigger finger can affect anyone, including children — a condition known as pediatric trigger thumb.

Symptoms of Trigger Finger

Trigger finger symptoms often develop gradually and may include:

• A clicking or popping sensation when moving the finger
• Tenderness or a small bump (nodule) at the base of the affected finger on the palm side
• Finger stiffness, especially in the morning
• The finger catching or locking in a bent position
• Inability to fully straighten the finger without help from the other hand

Symptoms are often worse in the morning or after periods of inactivity.

Treatment Options for Trigger Finger in Raleigh

Treatment depends on the severity of your symptoms and how long you have had the condition. We always consider non-surgical options first.

Rest and Activity Modification

Reducing repetitive gripping activities and resting the hand can allow mild inflammation to settle. A splint that keeps the finger in a straight position at night is often recommended for early-stage trigger finger.

Corticosteroid Injection

A steroid injection into the tendon sheath is one of the most effective non-surgical treatments for trigger finger. The injection reduces inflammation, allowing the tendon to glide freely again. Many patients experience significant improvement after a single injection, with effects lasting several months or longer. A second injection may be offered if symptoms recur.

Injections tend to be most effective for patients who have had symptoms for a shorter period of time and those without diabetes.

Trigger Finger Release Surgery

If injections do not provide lasting relief, or if the finger is locked and cannot be straightened, surgery is the next step. Trigger finger release is a quick outpatient procedure that involves making a small incision at the base of the affected finger to release the constricted portion of the tendon sheath.

Like our carpal tunnel procedures, we perform trigger finger release using the WALANT technique — wide awake local anesthesia with no tourniquet. This allows you to:

• Remain awake and comfortable throughout
• Move your finger during the procedure to confirm a full release
• Avoid the risks and recovery time associated with general anesthesia
• Return home the same day

Recovery is typically fast. Most patients can use their fingers for light activities within days and return to full function within 4–6 weeks.

Trigger Finger in Children

Pediatric trigger thumb is a condition where a child's thumb becomes stuck in a bent position. Unlike adult trigger finger, the pediatric version often does not resolve on its own and usually requires surgical release. We treat pediatric hand and finger conditions at our Raleigh practice — no referral is needed.

When Should You See a Hand Surgeon?

You should schedule an appointment if:

• Your finger is catching, clicking, or locking regularly
• You cannot straighten your finger without help
• Morning stiffness is affecting your daily activities
• A primary care steroid injection has not provided relief
• You have diabetes and are experiencing finger locking

Frequently Asked Questions About Trigger Finger

Can trigger finger go away on its own?

Mild cases may improve with rest and splinting. However, most moderate to severe cases require treatment — either an injection or surgery — for lasting resolution.

How long does a trigger finger injection last?

Results vary by patient. Many people experience relief for 6 months to a year or longer after a single injection. Patients with diabetes tend to have shorter-lasting results from injections.

Is trigger finger surgery painful?

The WALANT technique we use keeps you comfortable throughout the procedure. Post-operative discomfort is typically mild and managed with over-the-counter pain medication.

How soon can I use my hand after trigger finger surgery?

Most patients can use their fingers for light activities — such as typing and self-care — within a few days of surgery. Full recovery, including grip strength, typically takes 4–6 weeks.
